I am looking for diff functionality with Ruby for a project I am involved in. There seems to be a few available. The one I liked is differ. It allows you to do comparisons line by line, word by word, or character by character.

This got me thinking about the diff(1) command. With a little searching, I found that GNU diff and Solaris diff implement two different diff algorithms.

I attended a Scala talk at work today. Seems like an interesting language. I was a little disappointed that the talk was for only and hour and the speaker did not have a chance to delve into the concurrent aspects of Scala like Actors,etc.. While it does seem to speed up code writing, I am not sure how it will perform when its deployed. Yes, I know twitter uses them, and they are a poster child for scala, but I would like to understand the reasons why scala would be faster at deploy time.
Now time to plug my favorite language. Ruby Rocks!!
